Happy Aquarium puts 'Thriller' in your tank with Halloween Zombie Boy & Girl

Clearly borrowing from Michael Jackson's Thriller music video, the new Halloween Zombie Boy in Happy Aquarium is a premium, Limited Edition item that comes with its own dance moves. Each one costs 14 Pearls or 12 Facebook Credits ($1.20 USD). A Halloween Zombie Girl is also available for the same price, and she dances too.
